Title: Patterned articles and their manufacture
Inventor: COOPER IAN
IPC: A44C27/00
Filed: 1986-09-11
Abstract: Items of jewellery such as necklaces, bracelets, earrings are made by applying a liquid hardenable substance, such as a solution of a synthetic silicone rubber, to a fabric such as silk in a desired pattern.

Title: Method for forming hollow parts from a solid semi-finished material
Inventor: SCHWAGER ARIBERT
IPC: B21H1/18
Filed: 1986-12-01
Abstract: A workpiece 4 is clamped between a forming die 1 and a counter die 2. The workpiece 4 is rotated and an axial force 5 is applied to the die 1 with the result that it penetrates the workpiece. At the same time, the diameter of the workpiece is reduced using a ball or roller 6 which moves axially along the workpiece 4 to displace material formed by the introduction of the die 1 into the workpiece 4. The method may be carried out at ambient temperature. <IMAGE>

Title: Local-oscillator system
Inventor: ENGLAND MELVIN GERRARD
IPC: G01S13/24
Filed: 1987-04-07
Abstract: A local-oscillator system suitable for use with a frequency-agile pulse radar including spin-tuned magnetron (1). The local-oscillator system includes a fast-tuned local oscillator (in 9), the frequency (Fo) of which is adjusted by a summing amplifier in dependence on a coarse tuning signal and on a fine tuning signal. The fine tuning signal is derived by comparing the frequency of the oscillator with that of radiation in a current radar pulse, and the coarse tuning signal depends on the output of a frequency read-out system (6), associated with the magnetron of the radar, and on an error signal which is derived by a microprocessor from a plurality of fine tuning signals corresponding to earlier radar pulses. <IMAGE>

Title: Rotary thermal regenerators
Inventor: HRYNISZAK WALDEMAR
IPC: F28D19/04
Filed: 1987-04-07
Abstract: An exhaust gas extractor fan 1 and a rotary regenerative airpreheater are combined in one unit to extract heat from hot waste gases, for example of a heating appliance, and transfer it to fresh air before being used, partly or completely for instance for combustion purposes. Therefore the amount of fuel consumed by such an appliance can be reduced, having, apart from reducing fuel costs, the additional benefit of reducing air pollution. The regenerative airpreheater disc is preferably made from a ceramic material. The disc can be driven via a reduction gear by the motor of the extractor fan, or a separate motor, its speed being geared down to that of the disc. <IMAGE>

Title: Suppressed air-resonance loudspeaker enclosure
Inventor: PURVES COLIN GEORGE
IPC: H04R5/02
Filed: 1988-09-13
Abstract: A loudspeaker enclosure 1 has a driver fitted into each of its two opposite ends 2 in such a manner that the two driver diaphragms effectively form the ends of the enclosure and end panels actually exist. By virtue of the resultant pipe-like enclosure shape, if the length between the driver ends is greater than the maximum diagonal dimension across the end, then the major air resonance and its harmonics are established along the axis of the enclosure which is the greatest dimension. These dimensionally defined resonances are suppressed by the two moving diaphragms which is the end planes where oscillatory nodes will be attempting to form. Radial air resonances are similarly dimensionally defined and being of much higher frequency by virtue of the lack of substantial parallel planes and the smaller dimensions, may be suppressed, together with the higher oscillation modes, by using acoustic absorption materials in the conventional manner. <IMAGE>

Title: Telephone answering device
Inventor: HASHIMOTO KAZUO
IPC: H04M1/65
Filed: 1991-03-08
Abstract: A conventional telephone answering device (TAD) does not work properly if the handset of a telephone is picked up (perhaps by a child) during the particular period when a call signal is received but the TAD is not yet in operation. In the present invention, it is so arranged that even if a child picks up the handset of a telephone the TAD will function properly as long as the handset is hung up within a predetermined time period. Moreover, if the handset is picked up while the TAD is in operation but hung up within a predetermined time period, the TAD will continue the operation without being suspended. A changeover switch SW1 is provided to enable the TAD of the present invention to function as a conventional TAD, when desired. <IMAGE>

Title: Electro-optical detector using size invariant process
Inventor: SUTTON PHILIP
IPC: G08B13/193
Filed: 1992-07-02
Abstract: An electro-optical detection system for discriminating coherent or partially coherent radiation against an incoherent background in a field of view has a first reticle located in the path of the received light. A first lens L1 produces an optical transform of the first reticle 130 at a second reticle 131, both reticles preferably being picket fence type. A second lens L2 then produces an optical transform of the second reticle 131 and the resulting image is incident on an array of detectors which may be the 2D fibre array face plate of a CCD camera. The output of the detectors is connected to a signal processing circuit responsive to a characteristic image pattern on the array indicating presence of a coherent or partially coherent source in the field of view. The final image thus formed is independent on the size of the source of coherent or partially coherent light. <IMAGE>
